Since mine has the wide top 3/16, my question is how hard would it be to convert it over to the 1/8th upper? I've priced some and don't know poop on what's good, what's bad, what's a good deal ect..... I have noticed that if I had the 1/8th upper choices are endless so I thought I might buy one and if possible move all my parts over to it. I appreciate all advice
